(Cl. J-138) 2 Claims. 1

My invention relates to spinning frames, and more particularly to a combined saddle and oiler for the draft rollers of spinning frames.

A primary object of the invention is to provide a combined saddle and ciler for the upper draft rollers of spinning frames, which will more effectively provide the necessary lubrication, without the use of any wicks.

A further object of the invention is to provide a combined saddle and oiler, wherein the luorin cating oil is entirely enclosed within the oiler prior to its `appli-cation upon the roller, and therefore cannot run over the machinery or yarn.

A further object is to provide a saddle oiler which will effect a saving of oil and yarn, which are wasted with present types of oilers.

A further object is to provide an oiler which meters the oil directly and evenly upon the upper draft rollers at the point where it needed for lubrication.

A still further object of the invention is to provide a combined saddle and oiler which is sirnple, practical, and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same,

Figure l is a central vertical longitudinal section through the combined saddle and oiler, and showing the same applied to the upper draft rollers of a spinning frame.

Figure 2 is a plan View of the device as shown in Figure 1, parts omitted, and parts roken away.

ln the drawings, where for the purpose of illustration is shown a preferred embodiment of the invention, the numeral E designates generally a single set or stand of draft rollers of a conventional type of spinning frame. This stand 5 of draft rollers comprises lower draft rollers 6, and the usual upper draft rollers l, which are mounted upon a suitable frame 8, and adapted to be moved vertically into and out of `contact with the lower rollers 6. The lower and upper draft rollers e and 'l are cylindrical, and the yarn is drawn between the contacting cylindrical surfaces, as is well known.

The upper rollers 'I are maintained in engagement upon the lower rollers 6 by means of a combined saddle and oiler 9, which is held clown in the usual manner by an adjustable generally vertical strirrup Il), which is pivotally connected to a generally horizontal lever Il, pivoted to the 2 spinning frame as at I2. The free end of the lever Il carries a weight i3, which provides the necessary downward pull upon the saddle and oiler El. The combined saddle and oiled is thus held in frictional engagement against the rotating upper draft rollers l.

I will now describe in detail the combined saddle and cilcr il which embodies the present invention. rEhe combined saddle and oiler El comprises a unitary elongated body or chamber Hi, provided with a main longitudinally extending channel or bore i5. The body lli is formed of metal, and may have any desired shape in transverse cross section, such as rectangular, The main bore l5 is formed in the upper end i5 of the body ifi, and the bore l5 terminates short of the opposite end forming a trap or chamber for the lubricating eil. A suitable lubricating oil cup or reservoir i8 is mounted upon the end it of body ifi. This oil cup i8 includes a bottom lateral inclined discharge stern or nipple I9, which is screw threaded, and engages in an end screw threaded portion 2B of the main bore I5. Oil in the cup l is gravity fed into the bore l5. The oil cup i8 has a pivoted cover or cap 2l, to keep foreign mai-,tel1 out of the oil. Formed upon the bottoni of the body I4 are a pair of parallel spaced depending lugs or projections Z2, which are adapted to straddle the uppermost roller l, as shown. The lugs 22 serve to position the coinbined saddle and oiler 9 with respect to the upper rollers l and to hold it against longitudinal movement. The uppermost roller is of course freely rotatable between the lugs 22.

Near each of the upper draft rollers 'i the body is is provided with bottom lateral conically tapcred ports or oil discharge openings 23, 2d, and 25. These tapered ports 23, 2d, and E5 lead into the main bore i5, as shown. The tapered port 23 is disposed at the point where the bottom side of body ifi engages the adjacent roller l, and the port 23 is adapted to supply oil directly upon the roller l. All of the upper draft rollers 'l have grooves 25 formed in their cylindrical surfaces and near their longitudinal centers. The conibined saddle and oiler 9 engages the rollers l at these grooves 2S and the lubricating oil is applied only to the surface of the grooves 2%. Adjacent the center roller l, a small depending projection or boss 2l is formed upon the bottom of the body lli, and this boss 2l has a transverse cylindrically curved recess 28, 4which bears against the surface of groove 25. The boss 2l is provided with a small port 29, which leads to the tapered port 2t. Adjacent to the lowerinost roller 1, the body I4 has formed upon it a depending boss 30, provided with a transverse cylindrically curved recess 3I, which bears upon the groove 26 of adjacent roller l. A short bottom longitudinal groove 32 is formed in the bottom surface of boss 30 and leads into recess 3| from a countersunk port 33, which leads to the tapered bore 25.

Opposite each of the tapered ports 23, 24, and 25, the body I4 is provided with transverse screw threaded openings 34, which receive screw threaded valve elements 35, having conically tapered valves 36 to enter the ports 23, 24, and 25. The valve elements 35 are held in their selected adjusted positions by nuts 31, seated upon washers 38, as shown. The valves 36 are adjusted with respect to the ports 23, 24 and 25, so that the desired quantity of oil will be applied to the rollers I by the combined saddle and oiler.

Formed upon the top side of body I4, near the center opening 34, is an upstanding boss 39, having a longitudinal screw threaded opening 4B, to receive a stirrup adjusting screw 4 I. The head 42 of the adjusting screw 4I has an annular groove 43 formed in it, to receive the top of the stirrup I0, as shown.

In use, the combined saddle and oiler 9 serve to clamp the upper draft rollers 'I against the lower rollers 6, as stated. This creates considerable friction between the upper rollers 'l and the combined saddle and oiler. Therefore, the combined saddle and oiler is designed to apply oil to the grooves 26 of rollers 1, as explained. It is thought that the chief advantages of the combined saddle and oiler herein described, are set forth in the foregoing objects of the invention.

It is to be understood that the form of the invention, herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the inventiony or the scope of the subjoined claims.

Having thus described the invention, claim:
